Finally had a warm day, 38 degrees and basically no wind so I got the ceiling tore out and 2 of the panels cut.
Warning about RV Nation. They had the padded vinyl material. Started to order 3 yards of it and when i got into the checkout process, they were going to charge me $201 for shipping on $58 worth of product. Uhmm nope, ain't goona happen.
Found a place called All Vinyl Fabrics. They had a padded marine vinyl. Little more expensive, it cost me $75 but only $27.30 for shipping. And very helpful. I called them before ordering and he directed me to exactly what I was looking for.
Some pics of what I accomplished today are in a separate post.
